But I'm curious as to why you would want to set the MTU=8K?
Jumbo frames are typically set on OSA's at 8992, so unless this is strictly LPAR to LPAR on the same CEC, then "PATH MTU DISCOVERY" may be in order (or setting all IFs to the same MTU) to prevent segmentation if packets arrive from a OSA and are bound for the HiperSockets. It all depends on what packet routing you will be doing. Without knowing your OS's, applications or network topology its hard to advise..... mark ---------------------------------------------------------------------- For LINUX-390 subscribe / signoff / archive access instructions, send email to [EMAIL PROTECTED] with the message: INFO LINUX-390 or visit http://www.marist.edu/htbin/wlvindex?LINUX-390
